Also note that VLC usually tries to do everything it can to prevent 
framedropping. Framedropping should only occur during significant CPU 
load or if the CPU is too slow to decode the video.
If it does drop, it usually drops HARD. especially on mpeg4 style data, 
it usually drops a slew of frames. (but it will always be true to the 
original timeline of the video).

Best just make sure that you video doesn't encouter those situations.
